To who/in may concern:

Be a lmownthat i, wiLLnM A. raices,

citizen of .thefUnited States, residing at` counting mechanism operated thereby, a

' a phonograph. My inventionis of particu-- purposethat maybe served by this counting mechanism being the actuation of a brake or other` means for stopping the rotation of a record upon A:the oompletionof its run in lar service when employed inA connection with aphonograph thatincludes a `disc record supporting turn table which isprefe'rably itself employedfor effecting the applis x cation of .the brake.

.In the preferred embodiment of. my invention the counting device includes a threaded shaft having 'ya gear wheel forV turningl it,

this Iwheel beingrotated'by a threaded' for-14 mation' upon the periphery of thewturn ta-V blelyandV a rider iny threaded engagement with the shaftfand brought lthereby into actuating relation with the brake` or other record'stopping meansI when a record has been 1 played. There is desirably associated with the ridertwo reversely relatedv or oppositely` reading. scales which are `placed along-the line of .travel of theyrider for .denotingthe' number of 'rotations-of the turn tableLone scale being 4employed. to ascertain-the num-ll ber of ,revolutions a record Vmaires v to com;

I will explain my invention more 'l fully". by reference to the accompanying drawing illustrating 'one embodiment thereof andl in which Fig. "1 is a plan view of.venough ofna phonographgto illustrate the application` of my Fig. 2 is a sectional view on line2f2 of 1 meohanismfremoved. p

By mechanism whichisto be. described rider l2 "gradually, approachesfthe erin branch l0 and ultimatelyengages thesame whenV the record .hasy been nished,l said arm branch projecting slightly beyondI the'cir-'clev of the turntablewto` makeit-gacce'ssible for".V engagement by said rider. ,Thisrider in-' cludes, asa part thereof, a :nuo lfwhich'f-is in threaded engagement fwith a threaded shaftli, the shaftbeing rot-ated by' the turn table in a manner to be set. fQrthS-so as tol` bring the engaging part 12 of the rider into brake actuating engagement kwith the arm` branch 10. A gear wheel 15 is employed for l turningthe shaft 114C, the wheel and shaft being desirably Co-aXial with. the .wheel iniixed f relation to vthe shaft.y yThis-gear wheel isffenf gaged by a threaded formationpl providedA upon the exterior cylindricalsurfaceof ,the`

turntablerim 8. Thisspiral formation 16 constitutesa-threadwwhchsfin engagementwith the gear wheel l15 Awhereby, said'gearv wheel isturned` as the turn table is rotated.

The threaded formation -16 may be furnishedy the clips to enable them to perform their clamping function. t

As' a record is beinf played the rider will move "toward the le `t and ultimately will engage the portion 10 ofthe track tov aotuate the brake when the record is concluded.

determine the number of turns to be made by' The" records at present up'on `the market do not indicate the numberv of their revolutions required to lplay them, onwhich ac count Ithe users of my invention will have to the record in order that the rider may be adjusted to have lineal travel corresponding to theY varying extent of the rotation of the records. Sonie records require more or less lineal travel of the riders than others. To this end I p'rovide' two oppositely reading or reversely related scales 19, 20'. When the number of turns required'by the record is to be counted the rider is placed at the initial end of the scale"19 whereupon the phonograph is started, the rider being moved in a lineal directl twidrth tIIJ t'ablllll'til the phIj graph stopped at the conclusion of the `perforrii'alrice of a'r'ecord. Thegnumber of turns lis indicated. by. the mark upon the scale 19 with'which theindeir 21 (upon the rider) ,stops in register. The indexr 22, 'also carried npon the' rider, then placed in `register with that' scale mark upon the scale 20 that corresponds in number with the number of rotations indicated by the index 21. To' make the-rider readily adjustable along i the'jscales/in determining the place at which it should be set, it is caused to have 'separable engagement with the threaded portion of the shaft 14g.v To this endthe construction illustrated most clearly in Fig. 4 may be employed with a stem 23 projecting upwardly through the slot 24. between' ythe scales 19 4and 20,'this` stein terminating in a knobr 25 by means 'of 'which the rider may be readily lifted'from'v engagement withy theshaft and in opposition to thesp'ring 26 that normally maintains the threaded engagement of the rider, with lthe shaft.v The stem 23 also preferably has snug sliding engagement Awith the opposing edges ofthe scales so that these scales, vin conjunction with the spring, serve toy maintain the rider in normal position not' only with respect to the shaft 14g but also with respect to the brake' 10 of the brake arm 4. For simplicity'of construction the mounting leaf 6 is a continuation of the framework 27 which supports the scales.

illustrated, thejspring 7 will release the brake as soon as the rider is moved away from the record, whereby the record will be automatically started following the outward positioning movement'of the rider, the stylus having been previously adjusted to starting position. j

Thev c ounting'andl record stopping nieclraf nism herein disclosed does'notjemp'loy'the stylus for actuating it, themechanisrnjthat operates the phonograph operating thef *delll vice of my invention independently o-f-'theso stylus', an obvious advantage. W 4
